CLEANING DEVICE WITH INTERCHANGEABLE HEAD BACKGROUND OF THE INVENTIONField of the Invention The present invention relates to cleaning devicesof the type having interchangeable heads.

SUMMARY OF THE INVENTION The present invention is directed to aninterchangeable head cleaning device in which the handle and theinterchangeable pad are secured by the same resilient member.

The primary object of the invention is to provide a cleaning devicehaving an interchangeable head in which the head is secured to thehandle by the same member which secures the pad to the head.

Other objects and advantages will become apparent in the followingspecification when considered in the light of the attached drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of theinvention;

FIG. 2 is an enlarged fragmentary transverse cross section taken alongthe line 22 of FIG. 1, looking in the direction of the arrows;

FIG. 3 is an end elevation of the plate removed from the handle with nopad attached;

FIG. 4 is a perspective view of the resilient pad and handle securingmember;

FIG. 5 is a perspective view of the pad detached from the plate; and

FIG. 6 is a perspective view of a resilient pad used with a modifiedform of the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings indetail wherein like reference characters indicate like parts throughoutthe several figures the reference numeral 10 indicates generally acleaning device constructed in accordance with the invention.

The cleaning device 10 includes an elongate handle 11 having a shank 12extending axially of the lower end thereof and including a generallycylindrical right-angularly extending integral bar 13 on its lower end.

A generally rectangular flat plate 14 is provided with semicylindricalintegral rims 15 on opposite side edges thereof. The rims 15 open towardeach other forming semicylindrical recesses 16 completely along theopposite side edges of the plate 14. A cylindrical sleeve 17 ispositioned intermediate the rims 15 with its axis parallel to the rims15. The sleeve 17 is rigidly secured to the plate 14 by welding 18 orthe like.

A retainer wire 19 includes a pair of oppositely disposed spaced apartparallel legs 20 connected by a generally V- shaped central portion 21.The V-shaped central portion 21 has an upstanding semicylindrical bight22 formed at its apex. The wire retainer 19 is formed of resilientspring wire so that the legs 20 are normally urged outwardly away fromeach other with the retainer positioned against the plate 14 with thelegs 20 engaging in the recesses 16 ofthe rims l5.

A generally rectangular cloth cleaning pad 23 is adapted for use withthe plate 14 with the side edges 24 thereof engaged in the recesses 16.The legs 20 engage the side edges 24 to retain the pad 23 in contactwith the plate 14.

The bar 13 engages in the sleeve 17 to mount the plate 14 to the handle1 l for pivotal movement about the bar 13. The bight 22 of the retainerwire 19 is positioned adjacent one end of the sleeve 17 to hold theshank 12 to thus prevent the bar 13 from being slid out of the sleeve 17until the retainer wire 19 is removed.

In FIG. 6 a modification of the invention of FIG. I is illustrated as anattachment for the FIG. 1 device. A generally rectangular resilientblock 25 has a flat upper surface 26 and a flat lower surface 27. Thelower surface 27 has upwardly and outwardly tapering side portions 28.In the use of the cleaning device 10 for certain types of cleaning andpolishing it is desirable that the pad 23 be replaced with the pad 25.The pad 25 is resilient and can be used for scrubbing or polishingdirectly or may have a sanding sheet, polishing sheet or other materialsecured to its lower face.

The tapered side portions 28 of the pad 25, when attaching to the plate14, engage in the recesses 16 and are held therein by the legs 20 of theretainer wire 19.

Having thus described the preferred embodiments of the invention itshould be understood that numerous structural modifications andadaptations may be resorted to without departing from the spirit of theinvention.

What is claimed is:

1. A cleaning device comprising a flat plate with opposite side edgesupturned inwardly as rims extending toward each other and forminglongitudinal recesses facing each other, said plate having a sleevesecured to its upper surface, a flat flexible piece of material mountedon said flat plate and having its side edges extending into saidrecesses, resilient holding means engaging the material in said recessesreleasably securing said flexible piece of material to said plate,handle means including a shank with a right angle cylindrical barextending into said sleeve pivotally connecting said handle means tosaid flat plate, resilient means in alignment with said sleeve andspaced therefrom to prevent said bar of said handle means frominadvertently coming out of said sleeve, said resilient holding meansincluding a spring wire having a pair of oppositely disposed spacedparallel legs integrally connected by a V-shaped member, with saidresilient means comprising a semicylindrical upstanding bight integrallyformed at the apex of said V-shaped member.

2. A device as claimed in claim 1 wherein said oppositely disposed legsengage against the opposite side edges of said material in said recessessecuring said material in said recesses.

3. A device as claimed in claim 2 wherein said sleeve has its axisextending parallel to said rims and is positioned substantially midwaybetween said rims.

4. A device as claimed in claim 1, wherein said rims on said flat plateare semicylindrical in form.

5. A device as claimed in claim 1, wherein said sleeve has its axisextending parallel to said rims and is positioned substantially midwaybetween said rims.
